PS当前区域性返回屏幕上的键盘应用程序所使用的语言，这是不是我期待的。

P.S. current culture returns the language used in the on screen keyboard application, which is not the case I am looking for..

推荐答案

的情况下解决办法是获取前台窗口的键盘布局，然后将其应用到屏幕上的键盘，并且在平时的方式。

The solution was to get the Keyboard Layout for the foreground window, and then apply it to the on screen keyboard, and check for the language in the usual ways..

            IntPtr fore = GetForegroundWindow();
            uint tpid = GetWindowThreadProcessId(fore, IntPtr.Zero);
            IntPtr hKL = GetKeyboardLayout(tpid);
            hKL = (IntPtr)(hKL.ToInt32() & 0x0000FFFF);
            InputLanguageManager m = InputLanguageManager.Current;
            m.CurrentInputLanguage = new System.Globalization.CultureInfo(hKL.ToInt32());
            //IntPtr i = LoadKeyboardLayout(hKL.ToString(), 1);

            InputLanguage = InputLanguageManager.Current.CurrentInputLanguage.ToString();
